Question

The population mean and standard deviation are given below. Find the required probability and determine whether the given sample mean would be considered unusual.

For a sample of

n=61,

find the probability of a sample mean being less than

25.1

μ=25

and

σ=1.21.

Click the icon to view page 1 of the standard normal table.

Click the icon to view page 2 of the standard normal table.

For a sample of

n=61,

the probability of a sample mean being less than

25.1

μ=25

and

σ=1.21

nothing.

(Round to four decimal places as needed.)

Would the given sample mean be considered unusual?

The sample mean

▼

would not

would

be considered unusual because it has a probability that is

▼

less

greater

than 5%.
